Stereoscopes & Microscopes for Field, Desk & Computer

A Stereoscope is a device by which two images of the same object are taken at slightly different angles. When looked at without a stereoscope viewer the user is required to force his eyes either to cross, or to diverge, so that the two images appear to be three. Then as each eye sees a different image, the effect of depth is achieved in the central image of the three together, creating an impression of depth and solidity , or 3D.
